IPA IP 2022 Question 33
A question IPA Japan published in 令和4年度 ITパスポート試験 公開問題 問33, translated into English. ITPEC is based on the same exams.
Which of the following is the most appropriate term that represents the state or degree to which various people can operate, obtain, and use IT equipment, software, information, etc. in the same way, regardless of differences in users’ physical characteristics and abilities?
Explanation
Accessibility — the degree to which people can operate, obtain and use equipment, software and information in the same way, whatever their physical characteristics or abilities.
Accessibility asks whether everyone can actually use something: older people, people with impaired sight, hearing or movement, and people using assistive technology such as screen readers or voice input. Web pages are made accessible with text alternatives for images, enough colour contrast, text that can be enlarged and operations that work from the keyboard alone. It is close to universal design, which designs products from the start so that as many people as possible can use them.
Answer (a)
Why not others:
- •(b) Scalability — how easily a system can be expanded to handle more users or data, by adding servers or upgrading them
- •(c) Diversity — accepting and making use of people of different gender, age, nationality and background in an organization; it is about who is employed, not whether they can use IT
- •(d) Traceability — being able to trace an item’s history, such as a product’s production and distribution route, or a requirement through design and testing
Key rule: Usable by everyone regardless of physical characteristics or abilities is accessibility; growing with demand is scalability; tracing history is traceability.
